miRNA expression signature in lung during aGvHD. (A) Volcano plot showing the relationship between fold change and significance between the two groups. The horizontal dashed line indicates cutoff for significance p < 0.05 (−log10 p-value >1.3) and the vertical lines for fold change ≥1.5/≤−1.5. (B) Heatmap showing unsupervised hierarchical clustering of differentially expressed miRNAs in lung between control (n = 3) and aGvHD (n = 3) animals. Each column represents an individual rat. Relative fold change is indicated by the color scale (red: high; blue: low). (C) qRT-PCR analysis of miRNA expression in lung of control (n = 6) or aGvHD (n = 6) rats. Samples were normalized to endogenous controls and expression levels reported as log of 2−ΔΔCt ± SD. Significance was calculated using the Student’s t-test (two-tailed) with Welch’s correction.
